I have spilt milk on the carpet of my car, it stinks and I cant get rid of the smell, have used soda, biactal spray vinegar its still there even meths.
I'm sure you CAN get rid of it. But the smell is difficult to shift. In 1984, when I was 13, I threw a half eaten cheese sandwich to the back of my brothers built in cupboard. Today in 2004, 20 Years later - His room still smells of cheese!
